我有上面的查询，它使用带动态列的pivot作为存储过程的一部分。到目前为止，查询工作正常但我正在努力为每个返回的行添加一个授权总计列，这将是动态生成的列的总和（在变量@TimeByDay中）

我正在尝试关注这里的一篇文章https://www.codeproject.com/articles/232181/sql-pivot-with-grand-total-column-and-row但是有些怎样，我似乎无法让它发挥作用。

一般情况下：总计是 - 在大多数情况下！ - 表示层应该计算的东西。

如果必须这样做，您有两种选择：

让您的SP按原样返回SELECT 并再放一个SELECT，它只返回一行，包含您需要的所有SUM。根据您调用此工具的工具，只需一次调用SP即可读取多个结果集。
使用类似这样的内容

代码使用UNION ALL来添加总计。需要RowInx和排序以确保正确的顺序和最后一个位置的总计。

DECLARE @tbl TABLE (ID INT IDENTITY,val1 INT, val2 INT);
INSERT INTO @tbl VALUES (1,2),(3,4),(5,6);

SELECT ID,val1,val2
FROM
(
    SELECT ROW_NUMBER() OVER(ORDER BY ID) AS RowInx, * FROM @tbl
    UNION ALL
    SELECT 1000000,NULL,SUM(val1),SUM(val2) FROM @tbl
) AS t
ORDER BY t.RowInx

如何使用每行的总计列来旋转查询结果
